Fram HP4 Racing Oil Filter

FRAM Racing oil filters are designed to meet the standards of racing mechanics, engine builders and racing enthusiasts everywhere. The FRAM Racing oil filter is formulated to provide superior high performance engine protection.

Built to Last
What is the ideal design for a racing filter? We asked the pros and got this wish list for product features. 1. High flow rate, 2. Practically zero restriction and 3. High dirt stopping ability. Well, our engineers came back with the FRAM RACING oil filter. This design was track-tested to meet these requirements and those of our own filter engineers including many competitive racers.

High Oil Flow Rate
The oil film, or wedge, is the only element separating racing engine components that are moving at extremely high speeds. A high oil flow rate and high oil pressure are essential to deliver the flow volume necessary to maintain the oil film between moving metal surfaces. For this reason, the low restriction racing media of the FRAM RACING filter was designed for high oil flow.

Low Restriction
Ideally, racers would like zero restriction, but that is not possible. Oil flow encounters some restriction even as it moves through all engine passages. To create the smallest amount of restriction, the FRAM RACING filter utilizes up to three times the media used in passenger car oil filters for absolute minimum pressure drop with no sacrifice in filtering ability.

• Heavy-duty steel resists high pressure surges and external impact
• Low-restriction racing media designed for high oil flow
• Spiral-shaped centertube to provide protection against collapse
• Heavy gauge steel tapping plate to withstand high pressure flexing
• Screen-over bypass valve provides more protection against larger contaminants
• Relief valve developed uniquely for high oil flow racing conditions

The FRAM HP4 Racing oil filter fits these applications:
